Antlia

The Antlia IR Pass 685nm filter is an absorption filter that allows infrared light with wavelengths of more than 685nm to pass through. It nicely complements the Antlia 850nm IR-Pass filter.

The Antlia IR Pass 850nm filter is an absorption filter that allows infrared light with wavelengths of more than 850nm to pass through. It nicely complements the Antlia 685nm IR-Pass filter.

The Antlia Triband RGB Ultra filter is designed for light pollution suppression for OSC and Mono cameras. The spectral design selected the most substantial information in the RGB bands.

The Antlia H-alpha EDGE narrowband filter optimizes the FWHM (full width half maximum) to 4.5nm bandpass. The suppression of optical density (OD 5) on unwanted wavelengths and the excellent transmittance characteristics found in the Antlia 3nm Pro.

Antlia OIII 4.5nm EDGE filters are designed to deliver 85% transmission at the 500.7nm line that provides you with the maximum signal to reveal the faintest OIII nebulae structures.

High transmittance for working with both long focal ratios and fast optical systems (as fast as f/3 or maybe even f/2.8)!

The Antlia H-Alpha (Ha) 3.0nm filter is suitable for imaging H-Alpha emissions from nebulae, planetary nebulae and supernova remnants.

The Antlia SII 3.0nm filter is suitable for imaging SII emissions from nebulae, planetary nebulae and supernova remnants.
The 3.0nm bandwidth delivers a high transmission at a center wavelength of 671.6nm.

The out of band blocking specification of the new OIII Pro version is rated to OD5 (0.001%) which delivers an excellent SNR (signal to noise ratio) and effective cut-off rate to minimize interference from other wavelengths.
